This invention relates tormeters-and more particularly to gas meters ofthe type constructed of vcast iron and vemploying diaphragms Which are 'actuated by the iow of fluid through theVV meter soas to-operat'e an associated registering mechanism. -It has heretofore -been customary toso construct mevters of this typ'elthatgthe ,diaphragms were held in place by having theirlflexible peripheriesclamped betvveenthecircular faces of the meter body' andftheengaging `faces of 1 cast Viron covers which cooperated. With the associated diaphragms in enclosing kthe outer .measuring chambers' of themeter. .One of the disadvantages. resultingffrom this construction is occasioned by the fact that the 4material of Which the exible portions .of the diaphragms'` are constructed :is soporous as to permitY seepage of distillate and gas through the joint between the cast meter body and the cover, in which joint the diaphragme actasgaskets. i l l Anobject of thisinvention is` to provide a "meter-of the .type set forth of such construction and arrangement that no seepage' of distillate'orfgas can'takeplace through the joints between the meter proper; andthe covers. l* L i f A urthergobject isto provide a meter of Athe type set forth-of such construction so as to eliminate the use of the, diaphragm as 'gas Y, kets Vbetween themeterproper andthe'cox7` A stillfurtherobjectis'toprovide a diaphragm holder of such construction andarrangement lthat it canbe lappliedjto thewell known `castiron meters now in use so as'to .eliminate the presenceof Vthe diaphragms as gaskets in the cover joints.
